fix: show the caret in new, empty text (#932)
CanvasKit lays out no line for an empty paragraph, so the text editor found no caret until the first character was typed. A one-space line now gives an empty text's caret its height, and its alignment places it.

fix: share Figma's creation and grouping between editor and plugin API (#919)
* fix(core): start new layers with Figma's defaults in the editor and plugin API

The plugin API created bare nodes: frames, components, and shapes without fills, and lines and vectors without strokes, so scripts written for Figma drew nothing. Drawn lines also had a black fill instead of a stroke and were invisible. Both paths now share newLayerDefaults, recorded from Figma desktop 126: frames and components white with frames clipping their content, shapes #D9D9D9, lines and vectors a black 1 px stroke, text black. A stroke a script adds gets the 1 px default weight, and an empty vector has no render bounds.

* fix(core): combine variants as Figma does from the canvas and from scripts

The plugin API and the editor command each built component sets their own way, both with 40 px of padding and a grey fill. Figma's command pads the variants by 20 and outlines the set with a 1 px dashed #8A38F5 stroke; its plugin API wraps them exactly with no fill or stroke. One variantSetProps now places and styles the set for both, with a canvas or script style, and applyVariantProperties derives variant properties for both.

* fix(core): report group children in their container's space in the plugin API

Figma's plugin API places children of groups and booleans relative to the nearest real container and refits a group whenever a script changes one of its children. Ours reported group-relative positions and never refit, so scripts placing layers inside groups landed them in the wrong place. x, y, and relativeTransform now map through the groups around a node, and geometry changes, appendChild, insertChild, and remove refit the surrounding groups. The refit moves to Scene Graph as fitEnclosingGroups, shared by the canvas (with undo) and the plugin API.

* test(core): pass script-style strokes and typed components in parity tests

* test(e2e): expect Figma's default shape grey in the scene freshness spec

* fix(vue): draw lines by length and angle as Figma does

The Line tool sized a line as the box spanned by the drag. With the stroke a new line now gets, that box drew as a rectangle outline. A line now starts at the press point with the drag length as its width, no height, and the drag angle as its rotation, as Figma's Line tool makes it; Shift snaps the angle to 45° steps, as the docs already described, and a click makes a 100 px horizontal line.

* fix(core): give each new layer its own copy of the default paints

The defaults spread each paint shallowly, so every layer shared the colour object of the module-level default and editing one layer's colour in place changed the next new layer. Copy the paints with the Scene Graph copy helpers.

* fix(core): group, ungroup, and combine layers through shared code in the plugin API

The plugin API wrapped layers, ungrouped, made booleans, and made components from layers with its own code. Ungroup moved the children to the top of the stack, booleans were named "Boolean union", and a component made from a frame cloned its children under new ids. These now run through the editor's shared wrap, ungroup, and boolean functions, with the placement and defaults recorded in Figma desktop 126: a group or boolean without an index goes on top, ungrouped children take the group's place, booleans are named after the operation and filled with the default grey, a frame becomes a component in its place with its children, and any other layer is wrapped in a white component named after it. Undoing a wrap in the editor now returns each layer to its own place in the stack.

* fix(core): group, frame, combine, and make components from the canvas as Figma does

Recorded in Figma desktop 126: a container made from the canvas takes the topmost selected layer's place, Frame selection adds no fill and does not clip, a component wrapped around layers is white and takes a single layer's name, and a boolean is filled like its topmost operand, or its base for Subtract, without strokes. The canvas commands and the plugin API now share the wrap parent check, stack ordering, component rules, and boolean paints, and the plugin API's createComponentFromNode converts groups in place as Figma does. Undoing a boolean returns each operand to its own place in the stack.

* refactor(core): reuse translate when centering pasted layers

feat(ai): refine tool change and run views (#858)
* fix(app): animate menus, selects, and popovers as they open

The shared menu, select, and combobox content and the chat history and profile popovers appeared without motion; only tooltips and dialogs used the motion presets. A shared floating preset fades and scales them out of their trigger's side, and respects reduced motion.

They still close at once: during an exit animation the closing content kept focus, so a shortcut pressed right after choosing, such as undo, never reached the editor.

* feat(ai): compare a tool change's images with a split divider

The before and after images used a range input under a drawn line, and a second Compare/Highlight tab bar sat under the Changes/Input/Output one. A Reka splitter with the shared splitter handle now divides the two images, each drawn at the full width so the divider reveals one or the other, and highlighting the changed pixels is a toggle beside the changed-pixel share.

* feat(ai): name a run's earlier tool steps in its folded row

The folded row said only how many earlier steps a run took. It now lists them by name on one truncated line, with a count badge and a failure badge; its accessible name keeps the count.

* fix(ai): open tool calls to their full height at once

Reka measures a collapsible's content when it opens, but CodeMirror lays out its lines a frame later, and on the first call it was still loading. Every call animated to its height without the code and then snapped open, the first one further. LazyCodeViewer reserves the viewer's height from the line count before CodeMirror renders, and the card starts loading CodeMirror on hover or focus.

fix(core): load fontoxpath under Node's ESM loader (#824)
* fix(core): load fontoxpath under Node's ESM loader

fontoxpath is CommonJS, so Node exposes its exports only on default and openpencil query / MCP query_nodes failed with 'evaluateXPathToNodes is not a function'. Closes #787.

* test(tools): run an XPath query in the package runtime smoke check

The Bun-run unit tests take fontoxpath's named exports, so they never covered the Node fallback to default.

* test(tools): also run matchByXPath in the XPath smoke scenario

* refactor(core): import fontoxpath types through one namespace import

fix(canvas): show every top-level frame's name and select frames by it (#930)
* fix(canvas): show every top-level frame's name and select frames by it

Since clicks follow Figma's depth, the empty part of a top-level frame
that holds layers selects nothing, but a frame's name was drawn and
hit-tested only while that frame was already selected. Once a top-level
frame held layers it could not be selected from the canvas, as when one
frame is dragged into another and the outer frame is then out of reach.

Every frame on the page or in a section now shows its name, faded in
the canvas's text color and in the selection color while selected or
hovered, from the same viewport-culled label catalog as section and
component labels. Its name is a hit target whether or not the frame is
selected, so clicking it selects the frame, dragging it moves the frame,
and hovering it highlights the frame; locked frames stay out of reach.
SkiaRenderer.hitTestFrameTitle no longer takes the selected IDs.

* fix(canvas): draw and hit labels whose node is just outside the view

Label catalogs culled nodes by their own bounds, but frame, section, and
component names sit outside the node, so a node just below the view hid
a name that was on screen and could not be clicked. Label lookups now use
the viewport widened by how far labels reach. Presses and hover also test
component labels, then section titles, then frame names, the reverse of
the order they are drawn, so overlapping labels pick the one on top.

fix(fig): write text glyphs from the layout the renderer draws (#928)
* fix(fig): write text glyphs from the layout the renderer draws

Text without saved glyphs was written to .fig with outlines from a
character-by-character fallback: one unwrapped line at y = lineHeight,
no alignment, advances in pixels. Figma lays saved text out from that
data, so every wrapped OpenPencil label opened in Figma on one line, and
since saved glyphs now draw before the paragraph, OpenPencil did the same
after a reopen (#914). The Figma clipboard had a second writer with its
own shaping that matched outlines to characters by index.

One builder in @open-pencil/fig now writes derivedTextData for both. It
keeps glyphs a layer already has and otherwise asks the export runtime to
shape the text. Core shapes with the paragraph the renderer draws, so
lines, alignment, and baselines match, and takes each outline from the
glyph ID CanvasKit chose, so ligatures and contextual forms keep their
shapes. CanvasKit does not say which font drew a run, so outlines are
written only when the run's own font covers it; otherwise the layout is
written without outlines and readers lay the text out themselves.
Advances are in em units and the character offset map has one entry per
character, as in Figma's files.

The reader drops glyphs the earlier fallback wrote, recognised by its
offset map one entry longer than the text with every glyph on the one
written baseline, and any glyph set with a missing outline.

* fix(scene-graph): reflow resized text instead of stretching its glyphs

Resizing scaled a text layer's saved glyphs into the new box. That suits
path text, whose glyphs follow its path, but flat text reflows, and with
saved glyphs drawn before the paragraph a resized Figma text layer was
drawn stretched. Scale glyphs only for path text, including baked path
text that kept only rotated glyphs, and let the width change drop the
rest.

* docs(fig): describe how derived text is written

Figma draws saved text from derivedTextData even when it has the font, so the export docs record which glyphs the shared writer keeps, shapes, or leaves without outlines, and the units it writes. The README names the runtime service by what it now does.

* fix(fig): write text without glyphs when shaping fails

Glyphs are derived data, so a shaper error must not fail the .fig save or Figma clipboard copy that writes them. The builder now writes the layer without glyphs and logs a warning; the clipboard used to swallow the error silently, which hid a font-provider mismatch.

fix(desktop): pin every command line the app may start (#922)
* fix(desktop): pin every command line the app may start

On Windows the app starts npm-installed CLIs through cmd /c, and the shell scope let cmd take any arguments, so any code running in the webview could run any command. Each program now has a scope entry with its exact arguments, and Windows shims go through their own cmd-<name> entries with fixed /c <name> arguments. The agents and the MCP server no longer accept arbitrary arguments either. A test checks that every command the app starts has a matching entry on both platforms.

* test(desktop): expect Windows shims through their own scope entries

* test(desktop): check the executable of each shell scope entry

* test(desktop): allow no shell scope entry beyond the programs the app starts

An extra entry with a permissive validator passed the per-program checks.

refactor(fig): export the symbol readers and move the library tests home (#929)
The Kiwi codec types only symbolID, so every test reading symbolOverrides
or uniformScaleFactor repeated the same cast against a type the package
exported without the readers that go with it. symbolDataOf and
symbolOverridesOf are now exported and five call sites use them.

tests/engine/library exercises @/app/libraries, so it belongs under
tests/app by the placement rules; the shard list and the engine baseline
follow it.

feat(collab)!: sync layer trees as a CRDT and open each room in its own tab (#902)
* fix: stop ancestor walks from hanging on a parent cycle

A collaborator's concurrent reparent can leave two layers as each other's
parent. isDescendant, the design check's pageOf, and component sync walked
parentId without a bound, so applying such a change froze the editor.

Add SceneGraph.closest(), a bounded nearest-ancestor lookup, and use it for
these walks so bad data ends the walk instead of the tab.

* fix(collab): sync layer moves without parent cycles or stale child lists

Remote changes assigned each layer's synced parentId and childIds as plain
properties. Two peers moving layers into each other made them each other's
parent, a moved layer stayed listed under its old parent, reorders never
synced, and concurrent additions ended up in different orders or missing
from the parent's list.

Apply the tree after a change's properties: move layers to their synced
parents, skip a move that would make a layer its own ancestor and write the
layer's current parent and position back so every peer settles on it, and
derive each touched parent's childIds from its synced order followed by
unlisted children by id. Locally, a parent's child list syncs once after
each edit that adds, removes, moves, or reorders its children.

Fixes #888
Fixes #889

* refactor(scene-graph)!: move sibling order keys to scene-graph

Collaboration needs the same fractional keys as .fig export to order
siblings, and the app must not depend on @open-pencil/fig for them. Move
fractionalPosition, orderKeyBetween, and siblingOrderKeys to
@open-pencil/scene-graph/order-keys.

orderKeyBetween now always returns a key: when no printable key fits it
returns one above lo, which hasOrderKeyBetween detects, so callers no
longer branch on null. It takes an optional suffix, and siblingOrderKeys
can request one per key, so two peers inserting at one spot get distinct
keys. .fig export keeps its keys.

* fix(scene-graph): report instance child reorders as graph events

Instance sync sorted an instance's children in place, so nothing that
listens to graph events saw the new order; in a shared room the order
never reached other peers. Move each child that changes position with
insertChildAt, which reports the reorder.

* feat(collab): resolve the layer tree from each layer's parent history

Add a pure LayerTree for the shared document: each layer records every
parent it was moved under with a move counter and an order key. A layer
sits under its newest parent, ties broken by parent id; when concurrent
moves close a loop, the latest move in the loop falls back to the
layer's next entry until none is left, and a layer no parent can take
goes to its page (Evan Wallace's mutable tree hierarchy CRDT).

The result depends only on the entries, and resolution revisits only
changed, orphaned, and displaced layers. Seeded random runs check that
peers converge and that the incremental result matches a full one.

* fix(collab): sync layer moves as parent history and order keys

Each layer's shared map now records every parent it was moved under with
a move counter from a document-wide Lamport clock, and its order key
among siblings, instead of parentId and childIds. Every peer derives
parentId and childIds from these with LayerTree, so concurrent moves,
reorders, and additions merge, a loop from concurrent moves undoes its
latest move, and a layer whose new parent was deleted meanwhile returns
to its previous one.

A local edit's graph events are written once after the edit, in one
transaction. It records a parent entry for each layer whose parent
changed, a new entry for displaced layers on the touched paths so a move cannot pull
them back, and keys between the moved layers' neighbours with a random
suffix, so concurrent inserts at one spot get distinct keys. Remote
changes find their layers through each event's path, resolve only what
they touch, and move and sort layers through insertChildAt.

This replaces the childIds merge and the write-back of rejected moves:
a rejected move now resolves the same way on every peer from the shared
history, so nothing needs to be written back.

Fixes #888
Fixes #889

* feat(collab)!: convert saved rooms and keep mismatched builds apart

A room saved by an earlier build records parentId and childIds. When a
change brings in such layers, from this browser's storage or a peer,
convert them in one transaction: each layer's synced parent becomes its
only entry with counter 0, its position in the parent's synced childIds
becomes an order key, and the old fields go. The result depends only on
the document, so two peers converting at once write the same values,
and converting again writes nothing. The document's meta map records
treeFormat 2.

Builds that record the tree differently would corrupt each other's
rooms, so the collaboration namespace becomes openpencil/2 for Trystero
and the test relay alike, and each peer publishes its treeFormat in
awareness for future version messages.

* fix(collab): send a layer whose parents were all deleted back to its own page

Each layer's shared map records the page it was last placed on, and the
layers under a frame moved to another page are re-recorded. A layer whose
parent chain was deleted goes back to that page, falling back to the first
page only when the recorded one is gone. Saved rooms record pages when
they are converted.

* fix(collab): keep one root per room when peers edit their own documents

Joining a room keeps the joiner's earlier document in its graph, and an
undo or an edit made before the room arrived could still reach it. That
edit shared the joiner's root, every peer adopted it, and the room's
pages disappeared.

The room now records its root as claims in meta, each with the time it
was made, and every peer follows the earliest. Sharing claims the room,
and so does the first edit in a room nobody has shared, which now shares
the whole document as Share does. A peer shares only layers under the
room's root. Converted rooms claim the root with the most children.

Move counters must also be safe integers, so an oversized counter from
another peer cannot stop the move clock from advancing.

* fix(collab): rank root claims by how they were made, not by clocks

Root claims carried the claiming peer's wall-clock time, so a guest whose
clock ran behind the sharer's could still win the room with an edit made
before the room reached them. A claim now records whether it came from
Share or a converted room, or from the first edit in an unshared room;
a shared root outranks an edited one, and the lower id breaks a tie.
A claim also replaces an invalid value already stored for its root.

* fix(collab): keep every root claim through concurrent writes

A root claim was one key per root holding its kind, so two peers claiming
the same root by Share and by an edit at once kept only one of the two
values, and the shared claim could be lost. Each kind of claim on a root
is now its own key. Converting a saved room also claims its root unless
a shared claim exists, so a guest's earlier edited claim no longer keeps
the converted room from outranking it.

* fix(collab): mint layer IDs under a session of each editor window

Every editor window started its IDs at 0:1 from the same counter, so two
people adding layers to a shared room at once could mint the same IDs,
and one person's layers replaced the other's in the room. A joiner's
starting page also took the sharer's page ID and stayed in their list.

SceneGraph's default IDs now carry a session set with setIdSession, as
in Figma's sessionID:localID GUIDs. The editor picks a random 32-bit
session at startup, as Yjs does for each document's clientID; headless
tools keep session 0, so the CLI and MCP server give a file's layers the
same IDs on every run.

* fix(collab): let only Share set a room's root

A guest's first edit in a room whose contents had not arrived claimed
the room and wrote the guest's whole open document into it, images
included, and adopting the sharer's root later only hid it. Every room
starts with someone sharing a document, so a guest has nothing to claim:
only Share, or converting a saved room, now sets the room's root, as a
single value in meta, and a peer writes nothing until the root is known.

Unbinding a room also writes an edit still waiting to be sent, so a move
or deletion made just before leaving reaches the room.

* feat(collab)!: open each room in a tab of its own

Joining a room bound it to whatever tab was active, so a pasted link
could turn a saved file into the room's document, and a share link first
showed an editable blank document. A room is now a document: joining
always opens it in a new tab, or switches to the tab already showing it,
and only Share puts an existing tab's document into a room.

Every room tab owns its session (src/app/collab/rooms.ts and
session.ts), so several rooms can be live at once and keep syncing in
the background. The collaboration panel, presence, following, and the
/share/<id> address follow the active tab, and a canvas publishes its
cursor and selection only to its own tab's room.

A room tab derives its state: joining while its saved copy loads, then
waiting, with an explanation, while nobody who has the file is online;
live with others, or alone on this device's copy. Until the document
arrives the room's screen replaces the editor. Reloading a share link
rejoins it; leaving a room you joined keeps its file as a local unsaved
copy. "Connected" now means another peer answered. Pasted links and IDs
are normalised and validated, and invalid ones say so.

People join right away under a generated name such as "Teal Fox", with
a hint to set one; the one app-wide name is set in the share panel or
in Settings. On a phone, Share copies the room's link instead of making
a new room, and the presence popover shows the room's state.

* feat(desktop): open rooms from openpencil://join links and Home

The desktop app could not receive a share link: links point at the web
app, and openpencil:// only opened files. openpencil://join?room=<id>
now opens the room in a tab of its own. The native parser refuses
anything but a room ID, queues rooms for the frontend through
take_pending_rooms, and a second launch on Windows and Linux forwards
its link through the single-instance handler.

In a browser on a computer, the room's screen and the share panel offer
Open in desktop app, a link the browser hands to the app on click; it
never opens the app by itself. Home gains Join room…, which takes a
pasted room link or ID and opens the room in a new tab.

* feat(collab): set your name on the room screen

The room screen told someone joining under a generated name to set
their name but offered nowhere to do it before the file arrived. It now
has the same name field as the room panel.

* feat(collab): offer the desktop download beside Open in desktop app

A browser on a computer offers a room's openpencil://join link, which
does nothing where the app is not installed. The room screen and panel
now link to the latest release beside it.

* docs: describe joining rooms in the German, Polish, and Russian guides

Bring the translated collaboration pages up to the English one: Share as
the only way into a room, joining in a tab of its own, the waiting
screen, leaving with a local copy, and how layer moves merge. The
English page now names the panel's Leave room button.

* fix(collab): lay out the room screens like the app's empty states

The joining and waiting screens were a left-aligned card with a stray
spinner, a primary Copy link button beside an outline button and a
bare link, and a name field on a screen that lasts seconds. They now use
AppPlaceholder, centred over the tab: a heading, the explanation, the
two hints, secondary Copy link and Leave, a 'You'll appear as' line
whose Change opens a small rename popover, and the desktop handoff on
one muted line. The room panel lines its status dot up with wrapped
text, no longer selects the room link when it opens, and puts the
desktop links and Leave room on one footer line.

* fix(collab): show what a room tab is doing instead of a timed guess

A joined tab said nobody with the file was online five seconds after it
opened, whether or not it had reached the signaling service or met the
people already in the room. Its state now follows what the tab can
observe: connecting until the service answers, looking for people for as
long as that transport takes to introduce everyone, getting the file
from someone who says they have it, waiting when nobody who has it
showed up (naming other guests waiting too), and a can't-connect screen
when the service cannot be reached. Each peer says in its presence
whether it has the room's file.

* fix(collab): list other waiting guests with the explanation

The line naming other guests who are waiting too is information, not an
action, so it follows the hints above the buttons. Peers' hasFile flag
is optional, as older builds do not send it.

* fix(collab): send a canvas's cursor and selection to its tab's room again

Canvases read the editor through a proxy that follows the active tab,
and the room lookup by store never matched it, so pointer moves and
selections stopped reaching the room: collaborators lost each other's
cursors, selections, and page markers. The canvas now looks up its
room by its tab's own store, and its selection listener ends when the
canvas unmounts instead of piling up across tab switches.

* feat(collab): one avatar stack for the toolbar, the mobile pill, and pages

The toolbar, the page list, and the mobile HUD each drew the people in a
room their own way, and the mobile pill read 'Online: 3' in hard-coded
English beside a status dot too small to render. AvatarStack now draws
people overlapping with their agent counts and '+N', and every place
uses it: the toolbar wraps each avatar in its menu or hover card, the
mobile pill shows the room's state dot and the stack with a translated
name, and hovering a page with people on it opens a card with the stack
and who is there, with their agents, to follow. The mobile list is the
shared presence list, so it is translated and can follow agents too.

* docs: note the page hover card and mobile avatars in the changelog

* fix(collab): stop listening to a room once its tab leaves it

A session left its Yjs observers and its awareness listener attached
after dispose, relying on destroy() and the order of teardown not to
touch the tab again. It now removes them explicitly and clears its peer
list. Also fix a missing comma in the Polish collaboration guide.

feat(ai): revert, regenerate, and edit chat turns (#844)
* feat(core): add visual diff and patch apply tools

diff_visual renders two nodes at one scale through the existing raster export, compares them with pixelmatch, and returns the diff PNG with the changed ratio and region in source-node coordinates. It takes export_image's scale and maxEdge inputs. FigmaAPI gains a CanvasKit-backed raster codec and a pageId export option, so the app and headless CLI decode pixels and render nodes off the current page.

diff_apply applies diff_create and diff_show patches through the Figma API, validates every node before changing any, and supports dryRun and force. diff_show now simulates changes on a detached copy with the same property code. One serializer and parser back all three. diffDocuments compares two documents page by page by name path.

Image tool results now reach models as media with their metadata as text, for any tool rather than export_image alone. diff_create, diff_jsx, and diff_visual join the default AI tool set, and the diff tools are no longer hidden from WebMCP.

* feat(ai): show what each AI edit changed in its tool call

Reviewing an AI run meant reading tool output or undoing steps to see
what moved. Each document-changing call now rebuilds its page before
and after from snapshots taken around it, and diffs each top-level
layer's JSX with jsdiff, the same patch diff_jsx returns, to find the
layers it changed. After the call returns, the changed region renders
in both states at one size and pixelmatch highlights the difference.
The tool card opens on a Changes view with a before/after slider, the
pixel highlight, and a CodeMirror merge view of the JSX. Records are
saved with the conversation next to attachments.

Calls snapshot their page individually instead of through one shared
variable, so concurrent calls in a step no longer overwrite each
other's undo state. Core gains graphFromPageSnapshot for rebuilding a
past page state, diffPageLayersJSX and jsxPatch (now shared with
diff_jsx), renderRegionToImage for rendering two states of one region
pixel for pixel, and comparePNGs on the raster codec. Settings > Chat >
Change previews sets the stored image size or turns images off.

* feat(cli): add diff commands and agent diff guidance

openpencil diff create, jsx, show, apply, and visual run the Core diff tools on a file or the running app; apply writes back with --write or --output like eval. diff files compares two documents page by page and exits 1 when they differ.

The chat prompt asks the agent to edit in place and to verify risky edits against a reference copy with diff_jsx, diff_create, and diff_visual. The skill, CLI reference, MCP tool table, and a new Comparing Designs page document the commands and tools.

* feat(ai): render tool calls as summarized, highlighted cards

Every tool call showed only a status and its output as a JSON string,
so render calls hid their JSX, export_image dumped base64, and long
runs filled the transcript with identical rows.

A call now shows a one-line summary read from its input and chips that
select and zoom to the layers it touched, switching to the run's page
when needed. Expanded, it shows the JSX or script it wrote and its
JSON input and output in a read-only CodeMirror view, and exported
images inline. Render calls can be expanded while their input streams,
so the JSX appears alongside the canvas preview. Consecutive calls
beyond three fold into one row that keeps the latest call visible.

CodeMirror loads with the first expanded call. The code theme gains a
monospace fallback because the editor font variable is not always
emitted.

* feat(ai): let the chat AI diff its run against the starting state

The diff tools compare two nodes, so checking an edit meant cloning a
reference first, which the agent rarely did. diff_changes compares the
current page, or one node under it, with the page as it was before the
run first edited it, in diff_create's patch format. The app keeps that
page snapshot per run and exposes it through FigmaAPI.changeBaseline;
MCP and WebMCP have no run, so the tool is offered only to the AI chat,
where it is enabled by default and the prompt asks for it before
reporting.

* feat(ai): revert, regenerate, and edit chat turns

A reply that went wrong could only be undone step by step from the Edit
menu, and asking again meant typing a new message on top of the old
edits. Each run now keeps the undo entries its document edits push, and
the reply offers Revert changes while those entries are still the
newest on the undo stack, so it never undoes an edit made since. The
last reply can be regenerated, and the last message without
attachments edited and sent again; both undo the replaced reply's edits
first when they can.

UndoManager gains peekUndo so a caller can tell whether its entries
are still on top, and turn state follows the store's history:changed
event. The submission's chat dependency narrows to the members it uses.

* feat(core): diff and patch node trees as JSX attributes

diff_create, diff_show, diff_apply, and diffDocuments used a hand-rolled
`key: value` property format that covered about fifteen properties,
matched children by name path, and could not see moves.

Nodes are now projected to the attributes the JSX export prints, and
jsondiffpatch matches children (by ID or by name path) and detects
moves. Patches list `-`/`+` attribute lines per node plus moved, added,
and removed children. diff_apply checks every hunk first, applies
attribute changes through the renderer's prop handling, and changes only
the fields an attribute moves, so IDs, instance links, and other state
survive. diff_show takes JSX attributes instead of a JSON props object.

design-jsx gains sceneNodeAttributes, parseJSXAttributes, and
jsxNodeFields for this, and the export round-trip property table is
shared so every case is also diffed and applied. `diff files` loads its
documents in order so node IDs, and so its patches, are deterministic.

* feat(ai): report diff_changes as a patch diff_apply can replay

diff_changes printed a unified diff of the JSX, which agents could read
but not apply. It now diffs the run's baseline against the live page
with the patch engine, matching nodes by ID, so a rename is a changed
name and the output replays on the starting state with diff_apply. The
chat's Changes view keeps the JSX line diff, which is for people.

* chore: format the merged AI tool exports

* fix(core): keep diff_apply atomic and diff files honest about differences

- Added nodes render before anything else changes; if one fails, for
  example on a missing component, the rendered ones are deleted and
  nothing else is committed.
- A hunk with an attribute the renderer ignores fails instead of
  reporting "unchanged".
- diffDocuments reports `changed` from page statuses, and a page only
  one document has gets its status but no patch, since patches do not
  add or remove pages. diff files uses it, so an added empty page no
  longer reads as a match.
- diff files rejects a --page neither document has and a --depth that
  is not a non-negative integer, exiting 2; diff_create's depth is
  validated the same way.

* refactor(ai): drop the unused tool JSON slot and place the JSX summary comment

* refactor(ai): find a tool change's clipping region with jsdiff

clipChangedJSX scanned both JSX sources character by character for their common start and end. diffLines gives the unchanged lines before the first change and after the last; the app now declares the diff dependency Core already uses.

* fix(ai): keep a turn revertable when it ends with a view change

Every mutating AI tool pushes an undo entry, but a turn recorded only those of tools that change the document. A run that closed with viewport_zoom_to_fit left that entry on top of the undo stack, outside the turn, so Revert changes never appeared and Regenerate did not undo the reply. The turn now records every entry its run pushes.

* test(ai): give the fake chat Chat's sendMessage signature

The test type check added in #896 rejects a fake whose sendMessage requires text; Chat's takes an optional message, and the fake reads only its ID.

* feat(ai): keep reverted replies marked and tell the model about them

Reverting a reply undid its edits and hid the button, so the chat still read as if the edits were there, and the model's next request still carried the tool calls and results that made them, so it could build on nodes that no longer existed. A reverted reply is now marked in its message metadata, which conversations store, and shows Changes reverted. The next request carries a hidden note, in the way referenced nodes are passed, for each revert no request in the history has reported; a resent message reports again what the message it replaces reported. Edit > Redo bringing the edits back removes the mark. The revert bookkeeping lives in submission/reverts.ts, and ChatInstance moves to submission/types.ts beside ChatSubmission.

* fix(ai): keep reverted replies cloneable so the chat still saves

Marking a reply copied the chat's reactive message, so the copy carried proxied parts and saving the conversation failed with DataCloneError on the revert and on every save after it. The message is unwrapped before it is copied. The unit test's chat now keeps messages in a deep ref like @ai-sdk/vue's Chat and saves them synchronously like the history does, which reproduces the error. A new browser test drives the app's own tool loop with a scripted model: it reverts a real render, checks the mark, the note in the next request, that the chat saves without errors, and that the mark is still there after reopening the conversation.

* feat(ai): restore a reverted reply's changes from the chat

A reverted reply only said Changes reverted, so bringing its edits back meant Edit > Redo. While nothing has been edited since the revert, the reply now offers Restore changes, which redoes exactly its edits; the existing Redo listener then removes the mark. Once other edits close Redo, the reply stays marked. UndoManager.peekRedo mirrors peekUndo, so a turn can tell its entries are the next Redo applies.

feat(core): name the node type createInstance and detachInstance return (#918)
Both factories know what they built, but returned the bare proxy, so a
caller reading componentProperties, setProperties or isExposedInstance
had to narrow first — the instance surface is only spelled out on the
node types. Two test suites had each grown their own cast for it.

FigmaInstanceNode joins the other node types and is exported, and the
compatibility check names it instead of respelling the intersection.

Narrowing a return type is not a breaking change: a caller that held
the result as a FigmaNodeProxy still compiles.

test(fig): pin override and variable precedence to what Figma renders (#912)
* test(fig): pin override and variable precedence to what Figma renders

The rule that decides between a bound variable and an instance's text
override is not stated anywhere we control: an owner's consumption
entry binds the field when it carries variableData and clears it when
it is bare, and a binding beats a literal an outer owner recorded.

The archive is a six-node file authored in Figma for exactly these
cases, so the expected strings are Figma's own output rather than ours.
It replaces reaching for a 44k-record community file to check this.

* ci: pull the new fixture in the quick unit shards

The quick shards fetch an explicit list of small LFS fixtures, so a new
one arrives as a pointer and the fig shard fails parsing it.

fix(scene-graph): let generated IDs walk past large imported graphs (#915)
The default generator counts 0:1, 0:2, … across the session, and a .fig
import keeps its own 0:N GUIDs. After opening a file with more than 1000
consecutive taken IDs ahead of the counter, creating a node threw "The ID
generator returned 1000 IDs in a row that are in use".

A generator can only be exhausted once it returns more taken IDs than the
graph holds, so the limit is now that count instead of a fixed 1000.

fix: release documents when their tabs close (#904)
* fix(vue): release CanvasKit WebGL contexts when canvases go away

GetWebGLContext registers a canvas's context in CanvasKit's global
table, and the surface manager only called deleteContext on a failed
setup. Every destroyed canvas, and every surface rebuilt after a resize
or color-space change, stayed registered, and through the canvas
element CanvasKit kept the closed editor's component tree, store, and
graph alive.

The manager now keeps the handle and releases it on rebuild and
destroy. deleteContext also leaves CanvasKit holding the last current
context, so when the released context was current, a parking context
on a 1x1 offscreen canvas becomes current instead.

* fix(core): uninstall an editor's text measurer when it closes

setCanvasKit installed a global text measurer that closed over the
editor and its renderer, and nothing uninstalled it, so the last editor
to set up a canvas stayed alive after its tab closed and layout kept
measuring with its destroyed renderer. installTextMeasurer returns an
uninstall function; an editor uninstalls its measurer when disposed or
when its last renderer goes, and the most recent measurer still
installed takes over.

* fix(app): give editor stores their own effect scope

The first store is created during WorkspaceView's setup, so effects
created while building it joined the view's scope. Their cleanups
stayed registered there after the store was disposed and kept the
startup document alive for the life of the app. Stores now build inside
a detached effect scope that dispose stops.

* fix(app): follow the active tab in app-level editor subscriptions

App.vue provided a proxy that resolved to whichever store was active
when a property was read, so app-level composables such as the menu
and keyboard commands subscribed once to the startup store. They missed
events from later documents and kept that store alive, and Undo and
Redo availability came from the first document's history.

The app-level editor now moves event subscriptions to the active store,
and each tab's editor UI gets its own store through EditorTabScope, so
per-tab components stay bound to their document when it closes.
Selection capabilities read the undo history lazily instead of
capturing the first store's manager.

* fix(app): stop keeping closed documents in chat history and startup

The chat history kept the last editor it served only to compare it with
the next one; it now holds it weakly. WorkspaceView's first tab was a
top-level setup binding, which Vue keeps on the instance; it is now
block-scoped.

* test(app): check that documents closed in tabs are released

Opens a document in a new tab three times, closes each with discard,
forces garbage collection, and checks that weak references to the
closed graphs clear. On master all three graphs stay alive.

* refactor(app): provide the tab's store from a tab-keyed editor view

EditorTabScope existed only to provide a tab's store to its editor UI.
WorkspaceView now keys EditorWorkspace by tab, whose contents were
already remounted per tab, so the view provides the tab's store in its
own setup and the wrapper component goes away.

* fix(app): stop a store's effect scope when building the store throws

Effects created before the throw would otherwise stay alive with the partial store, which no caller can dispose.

* test(app): avoid empty callbacks in the store scope tests

fix(harness): start Pi sessions with MCP tools under Node (#897)
* fix(harness): start Pi sessions with MCP tools under Node

The desktop app always gives Pi OpenPencil's MCP server, and the
published companion failed every such session:

- @ai-sdk/harness-pi imports pi-mcp-adapter, which publishes only
  TypeScript sources, and Node refuses to strip types under
  node_modules. A module load hook now strips them for TypeScript
  dependencies only; Bun runs them as is. (vercel/ai#22040)
- pi-mcp-adapter imports @earendil-works/pi-tui but declares it as an
  optional peer, so npm leaves it out. The companion depends on it at
  the version pi-coding-agent uses, and a test keeps the two in step.
  (nicobailon/pi-mcp-adapter#805)
- Pi reports live-process resume, yet the service handed it state
  saved by an earlier session, and the just-bash sandbox cannot resume,
  so every later session with that ID failed. Live-process backends now
  start fresh and drop saved state.

Pi also installs the packages from a person's Pi settings with npm on
every session, writing npm's output to the companion's stdout. The
companion now keeps the real stdout for protocol messages, sends other
writes to stderr, and quiets npm on success. The app logs companion
stderr as diagnostics, since failures arrive as protocol errors.

* fix(harness): reject another backend's state before dropping it

loadResumeState removed saved state for a live-process backend before
createSession checked which backend owned it, so state saved by another
backend was lost instead of rejected. Ownership is checked first, and
only state that belongs to the live-process backend is dropped.

perf(scene-graph): give imported nodes the shape every node shares (#903)
* perf(scene-graph): give imported nodes the shape every node shares

createDefaultNode had no default for booleanOperation, and the .fig
importer sets that key on every node. A key outside an object's initial
shape turns it into a JavaScriptCore dictionary, so every imported node
had its own structure and dictionary property storage. Fully loading
material3.fig took 3.7 GB RSS in Bun; with the default it takes 2.8 GB,
with 0.5 GB less JS heap and 0.46 GB less memory outside it. V8 keeps
these objects fast either way.

The defaults now must name every SceneNode field, which the compiler
enforces, and a test checks that imported nodes carry exactly the
default fields. booleanOperation states the explicit undefined the
importer already stores.

* fix(scene-graph): require booleanOperation and compare node keys in order

Every SceneNode field is required except booleanOperation, so a typed
producer could still omit it and build a node with a different shape.
It is now required, with undefined still meaning no operation. The
node-shape test compares keys in insertion order, since JavaScriptCore
lays out the same keys added in another order as a different shape.

The changelog entry no longer quotes the Bun measurement as figures for
the macOS app and Safari, and records the type change as breaking.

fix: share CSS value parsing between dom-css and design JSX (#910)
* fix(core): let fill text share an auto-layout row

Fill frames grow and shrink from a zero flex basis, so fill siblings split a row's free space. Fill text only got flexGrow, and its measure function capped it at its stored width, 100px for new text, so seven fill labels in a 280px row each kept 100px and overflowed. Without a measurer, the fallback pinned that width and set no grow at all. Fill text now uses the same zero basis as fill frames on both paths.

* fix(design-jsx): read repeat() and minmax() in grid tracks

Track lists were split on whitespace, so columns="repeat(7, 1fr)" became the tracks repeat(7, and 1fr), read as fixed 0px and 1px columns that collapsed the grid. Tokens inside parentheses now stay together, repeat() expands its tracks, minmax() grows like its maximum, and a track the grid cannot express sizes to its content instead of to 0.

* refactor(scene-graph): parse CSS grid tracks with postcss-value-parser

design-jsx read repeat() and minmax() with a hand-written tokenizer and regexes, while dom-css already parses CSS values with postcss-value-parser. Track lists are now parsed in @open-pencil/scene-graph/css on that library, where both packages can use it, and design-jsx calls it. dom-css's hand-written declaration of the library's types is replaced by the types the library ships, which the shared module needs. The Scene Graph guide records that CSS values are parsed there.

* fix(dom-css): read shadows, borders, and lengths with the shared CSS parser

dom-css tried each word of a shadow as a color and parseColor turned the leading 0 into black, so a shadow written in the usual order imported black, and the headless runtime split the border shorthand on spaces, which cut rgb(226, 232, 240) apart and also gave a black border. Numbers, colors, shadow lists, and shorthand parts are now parsed in @open-pencil/scene-graph/css on postcss-value-parser. Every shadow layer imports, inset ones as inner shadows, a fully transparent color counts as none, and lengths in units that depend on context, such as % or em, are no longer read as pixels. tryParseColor gives the color or null, and parseColor builds on it.

* fix(design-jsx): read the shadow prop as a CSS shadow list

The shadow prop was split on spaces, so a color before the lengths or a spread made the shadow black, and only one shadow could be set. It now takes a CSS box-shadow list through the shared parser, and pixel lengths in style props use the shared number parser. A rem grid track now has its size instead of sizing to content.

* test: type grid track and shadow fixtures

The test type check added in #896 rejects the grid track tests that #866 merged, because their object literals widen sizing to string, so bun run check fails on master. The fixtures are now typed GridTrack and Effect values.

feat: open documents dropped onto the window (#906)
* feat: open documents dropped onto the window

Dropping a .fig, .pen, or other readable document did nothing: the canvas drop handler places only images and SVG files and swallowed everything else. The workspace now opens dropped documents in new tabs through the same path as File → Open, passing the file handle where the browser provides one, and reports files it cannot open instead of ignoring them. Images and SVG files dropped on the canvas are still placed.

* fix: classify each dropped file instead of matching File identities

DataTransferItem.getAsFile() may return a new File, so checking it against the canvas files from dataTransfer.files could miss images and SVG files and open them as documents in engines other than Chromium. Each extracted file is now classified on its own; a spec checks that an SVG dropped on the canvas is placed without opening a tab.

test: run each heavy unit test file in its own process (#899)
* test: run each heavy unit test file in its own process

`test:unit` and `test:unit:heavy` ran every file in one `bun test`
process. A heavy fixture file alone takes 2-6 GB, and what one file
keeps stays alive for the rest of the run. Quick files still share one
process; heavy files now run one per process, so the peak is the
heaviest single file. Coverage runs keep one process, since coverage is
collected per process.

stale-overrides parses material3.fig and joins the heavy list, and a
guard fails when a quick test reads a large fixture corpus.

* test(core): keep one material3 graph alive at a time in stale-overrides

The edited-document test held the exported reader graph, the reopened
graph, and the parsed node changes at once, and the first test's graph
was still alive when the second started. Each step now runs in its own
function and returns only what the next check needs, and the file
collects garbage between steps and tests. The checks are unchanged;
peak memory drops from 5.6 GB to 3.6 GB.

* feat: name the call and list every problem in validation errors

Tool arguments were checked with v.parse, whose error names only the first problem and neither the tool nor the argument, so a model that sent a wrong create_shape call read 'Expected string but received 42'. Tool arguments in Core, which AI chat, MCP, the CLI, and WebMCP all reach, the automation bridge's file commands, design JSX component properties, and gradient stops now throw a heading that names the call followed by v.summarize, which lists each issue with its path. parseToolArgs is exported for the app's own parses of tool arguments.

* test(design-jsx): pass a deliberately wrong property value through the types

The test checks what a script sees for a non-string instance property, which the Instance types reject at compile time.

* docs: say that MCP clients get the MCP SDK's validation report

The MCP SDK validates tool arguments against the registered schema before OpenPencil's handler runs, so an MCP client already received every problem with its path and does not see parseToolArgs' message.

test: typecheck the test suites and fix what that found (#896)
* build: typecheck the test suites

Tests were in no TypeScript program: no tsconfig included tests/** or
packages/*/tests/**, and bun strips types without checking them, so a
fixture could drop a required field and keep passing until something
read it.

@types/bun moves to the root because it was installed per package only,
and #cli-tests/* joins the paths the root config already carries.

* test: fix the type errors the test suites were hiding

Typechecking the tests turned up 1123 errors. Most were ordinary
strictness, but some were real: `NodeChange` bound to Figma's plugin
typings rather than the Kiwi codec in thirteen .fig tests,
materializeInstance was called with six arguments against five so the
blobs and source children were dropped, CanvasKit pixels were written
to a plain object that never reached WASM, and assertions were made
through accessors that do not exist, so they asserted nothing.

Fixtures that had quietly lost a required field now carry it, nullable
results are narrowed through the existing expectDefined helper rather
than assumed, and stand-ins for CanvasKit and the editor go through one
named helper instead of an unexplained cast at each site.

No test was deleted, skipped, or weakened, and no `any`, non-null
assertion, or ts-expect-error was introduced.

* docs: record what typechecking the tests established

Pins the app program's global types with an assertion rather than a
note, since an unpinned types list lets any root @types package decide
which platform src/** is judged against.

The two environment faults that look like code regressions — Vite's
dependency pre-bundle outliving a package rebuild, and heavy .fig
suites failing under load — go to the development docs, where an
explanation belongs.

* fix: align @types/bun and keep node types resolvable when extended

The root manifest declared a newer @types/bun than every package, which
check:monorepo rejects, and pinning the app program's types left them
unresolvable from a config that extends this one out of tree.

* fix: fail the test typecheck when the compiler itself fails

The gate matched diagnostics by substring, so a compiler or config
failure that named no test file printed a pass while having checked
nothing. Diagnostics are now split by whether they name a file: an
unscoped one is the run failing and stops the gate, a test file's is a
finding, and a source file's stays out by design.

Also drops the parameter planComponentConstruction never read, and
makes the inner-shadow verification script exit non-zero when it
renders no image instead of logging and succeeding.

feat: select layers at Figma's click depth (#900)
* feat: select layers at Figma's click depth

Checked against Figma desktop 126 with the same pointer input in both
editors. A click walks from the page down to the deepest layer under the
cursor and stops at the first layer that is not open: top-level frames
(on the page or in a section) and sections that hold layers, component
sets, and every ancestor of the selection are open. So a click inside a
top-level frame selects its direct child, the empty part of a top-level
frame or section selects nothing, and a selected layer's siblings and
cousins are one click away. Double-click goes one level deeper and
Cmd/Ctrl-click reaches the deepest layer.

A marquee started inside a top-level frame or section selects that
container's layers; from the page, a frame or section holding layers is
selected only when fully enclosed.

* fix(vue): compare marquee hits by canvas bounds

A marquee scoped to a rotated frame mapped only two corners into its space, and page-level enclosure used a frame's unrotated rectangle. Both now compare each layer's axis-aligned canvas bounds with the marquee, so rotated frames and their children are selected by what is drawn.

fix: match Figma when dragging, drawing, duplicating, and pasting (#894)
* fix: match Figma when dragging, drawing, duplicating, and pasting

Checked against Figma desktop 126 with real pointer input. A dragged layer
lands in the topmost unlocked frame, section, component, or instance under
the cursor, following rotation and clipping, and leaves its frame as soon as
the cursor does; groups, boolean operations, component sets, and locked
frames never take a drop, and a layer stays in its group unless it lands on
another frame. Space keeps parents, Shift locks an axis, and Control drops
into auto layout as an absolute-positioned layer. Locked layers stay put.

New shapes go into the frame under the start point, frames and sections take
in the unlocked siblings they fully cover, duplicates land in place (top-level
frames to the right), and paste keeps the copied position, centering an axis
that does not fit the selected frame.

* fix: match Figma for drag edge cases with components, groups, and auto layout

A second round of checks against Figma desktop 126, replaying the same
pointer input in both editors. A component set takes back only its own
variants, and components never go into other components. Groups and
booleans refit their children after a move or nudge, and a group whose
last layer leaves is removed. Pressing inside a selected frame, group, or
component set drags it instead of the layer under the cursor.

Auto layout children dragged out land where they are dropped, drawing
inside auto layout adds to the end of the flow, and wrapped frames insert
on the line under the cursor. Duplicates keep their names, and a main
component duplicates as an instance with Cmd+D or Alt-drag; a multi-layer
duplicate stays in place, and a lone frame in a section counts as
top-level.

* fix(core): refuse new shapes in the locked part of an instance

createShape redirected a refused parent through acceptingParent while keeping coordinates in the original parent's space, and still inserted the layer when the slot claim failed. It now takes the given parent, claims a slot when needed, and throws when the parent refuses children; drawing skips such parents before creating anything.

* chore: prefer es-toolkit helpers and lint the mechanical cases

AGENTS.md now names the es-toolkit helpers to reach for instead of hand-written equivalents, and the exceptions: a single clear native call or a measured hot path. The new open-pencil/prefer-es-toolkit rule rejects filter(Boolean) and Set round trips on arrays, the two cases that need no type information, and the existing 45 sites use compact and uniq. tools/ci/policy runs before dependencies are installed, so the rule is off there.

* refactor: deduplicate diagnostic categories with uniq

The codemod rewrote a filter(Boolean) inside a page.evaluate callback, which Playwright runs in the page where the compact import does not exist. The spec filters there again, and the rule now skips callbacks passed to evaluate, $eval, $$eval, evaluateHandle, addInitScript and waitForFunction, and filter calls on iterators from values, keys, entries and matchAll, which compact cannot take.

* test: write the prefer-es-toolkit cases like the other rule tests

Short standalone snippets, as in the base64 and JSON rule tests, instead of a declaration prefix on every case and inline object types.

feat: write variable-bound properties as tokens in exported code (#895)
* feat: write variable-bound properties as tokens in exported code

HTML and Tailwind JSX export reference the design tokens a layer is bound to, var(--color-primary) or bg-primary, instead of baking in their values. A binding becomes a reference only where the stylesheet resolves it as the canvas draws it: the layer still draws the value, the token's unit fits the property, and an attribute such as data-theme="dark" can put the element in the layer's mode. Standalone HTML includes the stylesheet for the tokens it uses, compiled into Tailwind's @theme for Tailwind pages.

* refactor: share the collection variable list and tighten token helpers

Read every variable in collection order through one collectionVariables helper built on es-toolkit's compact, used by the stylesheet and the token references, and map padding sides and color channels instead of repeating them.

fix(scene-graph): apply an instance's assignment to a late child (#884)
* fix(scene-graph): apply an instance's assignment to a late child

A component can gain a property-driven layer after an instance of it
exists. Cloning that layer copied the component's default and nothing
resolved the assignment the instance already made, so the layer showed
the default while the rest of the instance showed the assigned value.

Closes #849.

* fix(scene-graph): scope a property lookup to the component that defines it

An instance of a component that defines the id owns that reference even
when it assigns nothing, so the walk stops there instead of reaching an
outer instance's unrelated property of the same id.

Reported in review of #884.

* test(scene-graph): group the component property tests in a folder

Three siblings sharing the property- prefix is the domain-folder rule's
trigger; check:arch flags it.

* fix(scene-graph): resolve a property's owner through the instance chain

Only a component set's definitions reach its variants, so a component
nested in an ordinary component no longer claims the outer component's
property. An instance's link can point at another instance, so the
owner is resolved by following that chain to the component.

Reported in review of #884.

feat(scene-graph)!: let a SceneGraph take its ID generator (#887)
* feat(scene-graph): let a SceneGraph take its ID generator

The constructor accepts an ID generator, used for the root node and for
nodes, variables, and collections created later; generated IDs skip any
node, variable, collection, or mode ID already in the graph.

Refs #770

Signed-off-by: Marc Went <marc@went.io>

* perf(scene-graph): check mode IDs without allocating per created entity

Generating an ID spread every collection into a new array and scanned it
for each candidate, which runs on every createNode. Check the node,
variable, and collection maps first and walk the modes with an early exit.
An index of mode IDs is not kept because history snapshots, transfer, and
undo replace collection maps and edit modes in place, which would leave it
stale.

* test(scene-graph): cover injected ID generators and collision skipping

* docs: note the SceneGraph ID generator in the changelog

* test(core): keep reopened .fig GUIDs when a sibling is inserted before them

Refs #770

* test(collab): cover concurrent additions, same-property writes, and delete versus edit

Move the synced-store harness to tests/helpers/collab so the new cases
live in tests/app/collab, and let it bind graph events as a collab session
does. The cases edit both peers while disconnected and check the
converged graphs.

Refs #770

* fix(scene-graph): keep a collection's IDs apart and stop on an exhausted generator

createCollection asks for the collection and default mode IDs before
registering either, so a generator repeating a candidate gave both the
same ID. A generator that only returned taken IDs looped forever, even in
the constructor; it now throws after a bounded number of attempts.

* test: require the inserted GUID and a real disconnect in new tests

The GUID test passed even if export dropped the inserted layer, and the
concurrent-edit helper would have tested sequential sync had its peers
not been disconnectable.

* feat(scene-graph): create variable modes through the graph's ID generator

The editor minted added and duplicated modes as mode:<random hex>, so an
injected generator governed every graph entity except modes added after
a collection's first. SceneGraph.createMode mints the ID and adds the
mode; undo and redo replay it with addMode.

* test(core): type the reopened .fig buffer in the GUID test

* refactor(scene-graph)!: share random helpers and one component property ID

randomHex, randomInt, and randomIndex move from @open-pencil/core/random
to @open-pencil/scene-graph/random, so format packages can use them:
design-jsx and the MCP test server dropped private copies. Component
property IDs, written as prop:<random hex> in six places across Core and
design-jsx, come from createComponentPropertyId.

* docs: point the randomness rule at the shared ID and random helpers

feat(app): record runtime errors in diagnostics and make events readable (#874)
* feat(app): record runtime errors in diagnostics with their stack

Uncaught errors and unhandled rejections only showed a toast, Vue component errors after boot only reached the console, and a failed chat kept just its error name, so a failure like WebKit's 'Attempting to define property on object that is not extensible.' left nothing to diagnose. They now record a runtime.error, and chat.failed its code, message, and stack. Messages and stacks are scrubbed of URL queries, key- and token-like strings, and home folder names and bounded; AI SDK and provider errors keep no message, since it can quote prompts or responses. Copied diagnostics start with the app version, shell, browser, and language.

* feat(app): label, filter, and page diagnostics events

Every row in Settings → Diagnostics read 'Technical event': the summary looked labels up under diagnostics-prefixed keys the messages do not have, and only a few event kinds had labels at all. Each event now has a specific label and a short detail, such as 'Tool: render · 162 ms', 'Model step · <model>', or an error's message, expands to its recorded fields and stack, and the list filters by level and category and grows a page at a time. The copy action passes the environment header, which moves out of the recorder so tooling that compiles it needs no build-time globals.

* test(app): stream a reasoning reply in WebKit without page errors

Errors such as WebKit's "not extensible" TypeError appear only in that engine, so run a streamed reasoning reply there and fail on any page or console error.

* fix(app): scrub queries on bare paths in diagnostic errors

Only URLs had their query removed, so a message like 'Failed to load /Designs/app.fig?token=…' kept the token.

* fix(app): count diagnostics recorded before Settings opens

The event count and size updated only on new events, so the panel showed 0 events beside a full list.

* feat(app): record failed AI tool calls as problems, with the stack of engine errors

A tool catches what it throws and returns only the message to the model, so diagnostics saw a failed tool as an info event without details. The adapter now passes the thrown value to the tool log. A failed call is a warning; a TypeError, ReferenceError, or RangeError, which comes from a bug in OpenPencil rather than a wrong call, is an error with its message and stack. Other tool errors keep only their name, since their messages quote layer names and arguments.

* fix(core): log tool calls that return an error as failed

Most tools report a failure by returning { error } rather than throwing, such as describe with an unknown node, so the tool log and diagnostics counted them as successful calls while the chat showed them failed.

* feat(app): scrub cloud keys, JWTs, private keys, URL credentials, and emails from diagnostics

The scrubber caught keys by shape only, so 20-character AWS access key IDs, user:pass@ in URLs, and emails reached the log, and a JWT's payload survived because its dots split it into short runs. It moves into its own module with rules grouped by what they protect. The added credential formats follow gitleaks; keys the shape rules already catch, such as GitHub, OpenAI, Anthropic, and Stripe ones, get no separate rule. No maintained browser library fits: secretlint needs Node built-ins and adds at least 23 KB gzipped, and the PII redactors miss tokens. The scrubber is 0.8 KB gzipped.

* refactor(app): name how a tool call is recorded and import diagnostics from its index

* fix(app): record demo document loads in diagnostics

The preparation event's schema listed its kinds, phases, cancel reasons, and failure codes by hand and lacked demo-load, so every demo load failed validation and was dropped. The schema now validates against the same lists the preparation types derive from.

* feat(app): label document preparation events in Settings diagnostics

Preparation events showed their raw name, editor.preparation.finished, because the summary had no label for them. They now read as their kind, such as Switch page, with the outcome and duration below. Event names are a typed union and the labels a map keyed by it, so recording a new event without a label fails type-checking; names stored by older versions still fall back to the raw name.

* fix(app): keep source paths and scrub provider stacks, auth headers, and spaced home folders

Review follow-up. A provider error's message was dropped but repeated on its stack's first line, so it is now removed there too. The long-run rule redacted source paths of 40 or more characters, losing the failing file; a run with slashes now loses only its key-like segments. The bare-path query rule cut optional chaining such as a.b?.c and now needs name= after the question mark. Authorization header values in any scheme, credential assignments such as api_key= or password:, and home folder names with spaces are now scrubbed.

* fix(app): suppress repeats of alternating runtime errors

Repeat suppression compared each error only with the previous one, so a loop alternating between two errors recorded every occurrence. Recent errors are now kept in a small bounded map.

* test(app): validate copied diagnostics and wait for the copy to finish

Master now rejects JSON.parse with a type assertion, so the copied report is read through a Valibot schema. The uncaught-error test read the clipboard before its copy finished and could see the previous test's report; it now waits for the confirmation, as the export test does.

The PR review guidance workflow runs the script with plain Node from the default branch without installing packages, so the Valibot import added with the JSON validation work failed with ERR_MODULE_NOT_FOUND on every review and comment event. The script parses the event and pull request by hand again, accepting the null fields GitHub sends, and a test runs it under Node with nothing installed.

* fix(ci): install the review guidance tool's dependencies instead of avoiding them

Restore the Valibot schemas and declare valibot in the tool's manifest. The workflow now installs the tool's workspace from the default branch's frozen lockfile with the shared setup-bun action and runs the script with Bun. The event schema accepts the null fields GitHub sends for absent values.

fix(design-jsx): say what gradient helpers expect when stops are not an array (#881)
* fix(design-jsx): say what gradient helpers expect when stops are not an array

An AI agent called linearGradient with something other than an array of stops, and render failed with 'stops.map is not a function', which does not tell it how to fix the call. The helpers now validate their stops with Valibot and name the expected form, and the authoring reference shows the signature.

* fix(design-jsx): describe stops that cannot be shown as JSON

Review follow-up. JSON.stringify throws on a bigint or a circular object, so such a call failed with that error instead of the gradient's expected form.

* fix(design-jsx): word gradient stop errors from the Valibot issue

Review follow-up. The message now names the helper as a call, as the paint helper option warnings do, and ends with Valibot's description of what was wrong, which already says what it received without serializing the value. A stop that is neither [color, position] nor { color, position } names both forms and its index.

Copy a collection as CSS custom properties or a Tailwind v4 theme from the variables dialog, print it with openpencil tokens, and rebuild design_to_tokens on the same generator. Default modes go in :root or @theme, other modes override under their condition, and aliases are declared again in each mode scope so they follow it.

* fix: give modes that slug alike their own selector and variant

Two modes in one collection whose names reduce to the same slug, such as Dark and dark!, shared one default selector and Tailwind variant, so the later mode silently overrode the earlier one. Slugs are now numbered in mode order, as variable names already are.

refactor: define OpenPencil plugin data in one typed registry (#878)
* fix: validate parsed JSON at untrusted boundaries with Valibot

Clipboard HTML, library revisions from shared storage, MCP and automation
WebSocket messages, the MCP discovery file, sidecar output and AI/MCP tool
arguments were JSON.parse'd and cast to their expected types, so a
malformed payload reached the document or crashed paste. They now go
through v.pipe(v.string(), v.parseJson(), Schema), which reports bad JSON
and a wrong shape as the same validation failure.

The path_set tool rejects an invalid VectorNetwork and shares its parser
with create_vector. The CLI library catalog validates its files and runs
revisions through the same size, identity and content-hash checks as the
app; reading image bytes as index-keyed records also stops them coming
back empty. Hand-rolled typeof readers for plugin data, document metadata,
caches and preferences become schemas with their behaviour preserved, and
readCacheJSON takes a schema for its payload.

open-pencil/no-unvalidated-json-parse rejects type assertions on
JSON.parse results other than `as unknown` in src and packages/*/src.

* refactor: validate parsed JSON in tests and tooling

Extend open-pencil/no-unvalidated-json-parse beyond source: tests, helpers and repo tooling now parse JSON through Valibot schemas instead of asserting a type. The shared fixture reader returns a validated object; its old array annotation never matched the fixtures.

* refactor: define OpenPencil plugin data in one typed registry

Every plugin-data key OpenPencil writes is now a field of OPEN_PENCIL_PLUGIN_DATA in scene-graph, with the Valibot schema that reads it; readPluginData and withPluginData replace per-key constants, JSON.parse and hand-matched pluginId/key filters across fig, core, and vue. Moving OkHCL onto it fixes picking a colour rewriting the layer's other plugin data as OkHCL entries.

feat: create, fill, and edit slots (#862)
* feat(app): add slot property controls and a shared picker

AppPicker is a searchable, grouped list that opens beside the properties
panel, built on Reka's popover and listbox so search keeps arrow-key
navigation. It has comfortable rows with a thumbnail and description and
compact rows for plain names, plus an optional footer action.

The slot property row shows whether an instance's slot is Default or
Modified, its item count, its limits with a checklist popover, Add
instances on AppPicker, and Reset slot and Delete contents. These are
presentational; wiring them to the editor follows. Strings are English
only until the locale files catch up.

* feat(app): open variable, style, and instance-swap choices in the shared picker

The variable binding picker, the shared style fields, and instance-swap
properties now open AppPicker: a titled panel beside the properties panel
with search that keeps arrow-key navigation, a check on the current
choice, and footer actions. Variable binding keeps its detach and
create-variable actions. Instance-swap choices list the property's
preferred components first; instanceSwapOptions keeps the preferred flag
it already computed. AppPickerField gives select-shaped fields the same
picker with a combobox trigger.

* feat(core): edit instance slot content

Only an instance's slots take layers now. slotScope classifies a parent as
free, a slot of an instance, or the locked rest of an instance. Moves,
reorders, layer-panel drops, paste, duplicate, and instance creation
claim an untouched slot first, as Figma does on the first edit, and
refuse the locked part; drops over it land in the instance's parent.
Claiming keeps the layers but unlinks them from the component and moves
the instance's overrides on nested instances onto those instances.

Reset slot, Delete contents, and Add instance are editor actions, each
one undo step that restores the instance's subtree. A canvas drop or
reorder that claims a slot undoes together with the move.

* feat(app): show and edit slot properties of the selected instance

The component properties section lists each slot of the selected instance
with its state, item count and limits, and adds instances, resets or clears
its content through the editor's slot actions. The slot model lives in the
Vue SDK as useSlotProperties.

* feat(app): outline slots on the canvas and mark them in the layers panel

Hovering or selecting a component, an instance, or a layer inside a slot
draws its slots with a dashed pink outline and tints empty ones. Slot
frames are selected and hovered in pink and show a dashed-square icon in
the layers panel.

* test(app): cover slot outlines with canvas snapshots

* feat(app): translate slot and picker strings

* docs: note slot editing and the shared picker

* refactor: share slot test and story setup

* refactor(app): name the picker's header prop heading

* feat(core): create, configure, and remove slots on main components

A frame of a main component becomes a slot through a SLOT property
named after it; other sibling layers are first wrapped in an auto
layout frame. Slot settings and removal are single undo steps.
Instances now follow the component's property bindings on sync, so a
slot created or removed on the component reaches existing instances.
Slot helpers move to a slots domain folder in Scene Graph and Core.

* feat(app): create and configure slots from the menu and properties panel

Create slot joins the canvas context menu for layers of a main
component. A Slots section on main components and their frames
renames slots, sets their description, layer limits, and preferred
components, and removes them.

* fix: keep slot claims in the same undo step and refuse wraps inside instances

Creating an instance and pasting HTML now batch the slot claim with the
edit. Undoing an added slot instance restores the previous selection.
Grouping or wrapping layers in the locked part of an instance is
refused, and a section that cannot move no longer claims a slot. The
picker clears its search however it closes, and its close and slot
actions labels are translated.

* feat(core): create and inspect slots through the plugin API

component.createSlot() adds a 100x100 frame named Slot, Slot 2, and so
on, bound to a new SLOT property, as live Figma does. Slot frames read
type SLOT, resetSlot() restores an instance slot's component content,
and limitViolations reports BELOW_MIN, ABOVE_MAX, and
HAS_NON_PREFERRED for instance slots. addComponentProperty and
editComponentProperty take a description and slotSettings, a cloned
slot is a plain frame, and componentPropertyReferences uses property
keys in both directions. The limit checks move to Scene Graph so the
Vue SDK and the plugin API share them.

* fix: keep nested slot content across swaps and read nested instance properties

A nested instance points at the instance it was cloned from, so its
component properties resolved to nothing. Properties now resolve through
those links to the main component, and a swap or variant switch parks
the slot content nested instances own and restores it into nested
instances of the same names, as live Figma does. Plugin appendChild and
insertChild claim the slot they add to and refuse the locked part of an
instance with Figma's error.

* test(core): record resetSlot on a main component slot; fix the Slots roadmap row

* fix(core): refuse deleting layers outside an instance's slots

As in Figma, delete and plugin remove() leave an instance's own layers
and its slot frames alone, while removing slot content claims the slot
in the same undo step as the delete.

* test(app): wait for the bulk rename dialog to close before the next shortcut

* feat(app): unify add, remove, and settings controls in the properties panel

A section's + adds an item and a row's - removes it everywhere: grid
tracks and variant properties now follow the fill and effect lists, and
the header + of a component set adds Property 1 ready to rename instead
of an inline form. Removing a variant is Delete, as for any layer.
Row settings share the sliders icon, the variables button opens with
its own icon, every icon button requires a label, and the instance
header buttons use sentence case. Create Slot joins the app menu.

* docs: note the unified properties panel controls

* feat(app): animate floating panels alike and share the severity icon

Popovers, menus, selects, comboboxes, and pickers now fade and grow in
from the side they open on and fade out on close, from one motion
preset that respects reduced motion; tooltips keep the tooltip preset.
SeverityIcon and its colours move from the design check to shared
feedback UI, and slot limits use them, so a broken limit reads like a
design-check warning.

* docs: note consistent popover and menu animation

* feat(app): give every floating panel one surface and close it at once

Popovers, menus, selects, comboboxes, pickers, presence cards, chat
history, and the issue tooltip share one rounded surface with a 1px
ring that outlines it in both themes; one-line tooltips keep a compact
shape with the same edge. The select theme's radius and elevation
options and local shadow overrides are gone. Panels still grow in from
their side but now close immediately: a fading modal menu kept blocking
the canvas and shortcuts until it unmounted.

* fix(app): keep a reopened context menu open and name option-drag undo Duplicate

Closing the canvas menu hands focus back to the canvas; when that
landed just after a quick reopen, the new menu closed as focus moved
outside it. Shortcuts no longer wait for a panel that is already
closing, and an option-drag duplicate that claims a slot is undone as
Duplicate rather than Move.

* test(app): wait for menus and popovers to close before the next key

* fix: validate parsed JSON at untrusted boundaries with Valibot

Clipboard HTML, library revisions from shared storage, MCP and automation
WebSocket messages, the MCP discovery file, sidecar output and AI/MCP tool
arguments were JSON.parse'd and cast to their expected types, so a
malformed payload reached the document or crashed paste. They now go
through v.pipe(v.string(), v.parseJson(), Schema), which reports bad JSON

The path_set tool rejects an invalid VectorNetwork and shares its parser

caches and preferences become schemas with their behaviour preserved, and
readCacheJSON takes a schema for its payload.

open-pencil/no-unvalidated-json-parse rejects type assertions on
JSON.parse results other than `as unknown` in src and packages/*/src.

* refactor: validate parsed JSON in tests and tooling

Extend open-pencil/no-unvalidated-json-parse beyond source: tests, helpers and repo tooling now parse JSON through Valibot schemas instead of asserting a type. The shared fixture reader returns a validated object; its old array annotation never matched the fixtures.

* fix: validate clipboard geometry bytes, library images and model catalogs

Clipboard geometry blobs and library image bytes must be bytes at contiguous indexes, so out-of-range or gapped values are rejected instead of silently becoming different geometry or images; serialized library nodes must carry source metadata. The models.dev and OpenRouter responses are validated like their cached copies, and activate-tab rejects a CDP frame it cannot read instead of hanging.

* refactor: extend the JSON validation lint to .json() results

no-unvalidated-json-parse now also rejects type assertions on Response, Bun.file and shell .json() results, the same unchecked parse in another form. MCP server tests read /health through a validated readHealth helper and discovery files through parseDiscoveryInfo; the remaining tooling reads its JSON through schemas.

* test: validate the RPC request body in the CLI app export test

feat: control documents, history, settings, and tools from the CLI and MCP (#871)
* fix(app): record MCP and CLI structural edits as undo steps

The automation bridge ran non-atomic tools, render, and eval without an
undo entry, so Edit > Undo could not revert layers an MCP client or the
CLI created, deleted, or rearranged. Snapshot the page around these
edits as the AI chat does, and skip the entry when nothing changed so
read-only scripts leave the history alone.

* feat(app): activate documents, undo, redo, and change settings over automation

Add activate_document, undo, redo, get_settings, and update_settings to
the app's automation bridge. Settings cover appearance, snapping, canvas
rendering, recovery, and chat preferences, validated with Valibot and
applied through their owning stores; credentials, models, MCP
connections, storage, and tool access stay out of reach.

* feat(mcp): expose document activation, history, and settings tools

* feat(cli): manage documents, history, settings, and tools in the running app

Turn documents into a command group (list, open, new, save, close,
activate), add undo, redo, and settings get/set, and add tool
list/describe/call so every MCP tool runs from the shell, against the
running app or headlessly on a file.

* docs: document app control from the CLI and MCP

* fix: never prompt in the app from automation closes and saves

close_file opened the app's Save changes dialog, which an agent cannot
answer: the call timed out and the dialog stayed open. It now fails on
unsaved changes unless the caller passes unsaved "save" or "discard"
(CLI --save or --discard). save_file and new_document no longer open a
Save dialog for a document that was never saved, report a failed save
as an error, and leave the document untouched when the path is refused.

* docs: describe non-interactive close and save

* fix: address review findings in app automation

Keep a document's source when a save to a new path fails, report
vector-edit undo and redo no-ops as unapplied, echo only the applied
patch from update_settings so writing cannot read settings, reject
tool call --write/--output without a file, and stop settings get from
following inherited keys.

* fix(app): record render undo on the page that receives the layers

A render into a parent on another page was snapshotted against the
target page, so undo left the new layers in place. Snapshot the page
that contains the parent instead, and document that eval edits made
after switching pages stay outside the undo step.

* feat(app): limit automation undo to its own steps and expose design check settings

The undo history is shared with the person in the editor, so an agent's
undo could revert the user's last edit. Automation undo and redo now act
only on steps made through the bridge, and only while they are newest;
otherwise they fail and leave the history alone. Vector edit mode's
session history is off limits entirely. Settings automation also covers
the design check preferences that landed on master.

fix: export layers and pages that are not on screen in app mode (#877)
* fix(automation): export layers from a page that is not on screen

The app's raster export rendered against the page on screen unless the
caller passed a page, so MCP export_image with ids on any other page, or
with page_id naming another page, failed with "Raster export selection
must stay on a single page". Automation shares one app between clients,
so the page on screen says nothing about what a request means.

Render on the page that holds the requested layers instead. The user's
view and selection stay where they were.

* fix(cli): export the requested page from the running app

`openpencil export --page` never reached the app: `exportViaApp` only
forwarded `--document-id` and `--page-id`, and the app's `export` RPC
exported the given nodes or the selection on screen, ignoring the target
page. `--page` and `--page-id` therefore exported whatever was selected.

The CLI now resolves `--page` to a page ID through `list_documents` and
asks for a page-scoped export. The app answers a page-scoped export with
the layers of the target page, loading a `.fig` page that has not been
shown yet without switching to it.

CLI tests address the package source by `#cli/`, as Core and fig tests
already do, so the alias owner widens to the whole package.

* fix(automation): prepare fonts and layout for a page exported off screen

A page export loaded the layers of a page that had not been shown, but not
its fonts or layout, so text and auto layout could render differently from
the screen. preparePageNodes runs the same font and layout pass as a page
switch, once per page, without switching or superseding a switch.

The CLI export test now writes its own discovery file, so it no longer
replaces or removes the record of an app that is running.

* fix(automation): prepare a .fig page before running a tool on it

A `.fig` opens with only its first page populated; the others get their
layers, fonts and layout when first shown. The automation tool handler built
its FigmaAPI on the target page without loading it, so MCP tools aimed at a
page nobody had opened (`page_id`) saw an empty page: find_nodes found
nothing, export_image reported "No visible nodes to export", and create_shape
added a shape to a page that then held only that shape.

Prepare the target page first with preparePageNodes, as page exports do:
layers, fonts and layout, once per page. The page on screen does not change.

* fix(automation): render explicit export IDs on the page that holds them

Since the visual diff tools, the automation FigmaAPI passes its target page
with every raster export, so export_image with IDs from another page asked to
render them on the target page and failed with "Raster export selection must
stay on a single page". The page now names which layers to export only when no
IDs are given; an ID list is rendered on its own page.

* fix(core): share one off-screen page preparation between concurrent callers

Two concurrent preparePageNodes calls for the same page both populated it
and resolved its fonts, and the font manager's blocked-node set has no
reference count, so the first to finish unblocked text the second was still
resolving. Callers now share the in-flight preparation, which is kept once
it succeeds and retried after a failure.

preparePageNodes also reports whether the page is ready, so a caller can
refuse to run on a page whose document was closed or replaced mid-way
instead of acting on a page with no layers. Its unused options are gone:
one caller's signal cannot cancel a shared preparation.

* fix(automation): prepare the target page once for every command

Preparing an unshown .fig page lived in the page export handler, so explicit
export IDs, export_jsx, eval, tools, and the RPC fallback still saw such a
page as empty. The request dispatcher now prepares the resolved target page
before any page-targeted command, and stops with an error when the page's
document closed while it loaded.

* docs(changelog): fold the off-screen page fixes into one entry

* refactor(automation): rely on the dispatcher to prepare a tool's target page

The request dispatcher now prepares the target page before every
page-targeted command, so the tool handler no longer does it itself. The
tests run tools through the dispatcher, which is where that guarantee lives.

* docs(changelog): drop the tool entry now covered by the off-screen page fix

fix(core): save an unedited worker-opened .fig instead of hanging (#880)
* fix(core): save an unedited worker-opened .fig instead of hanging

Saving a .fig that was opened through the session worker and not edited
yet never finished. The export asks the worker for the original archive,
but the reply listener lived in port1.onmessage, which
registerFigPopulationWorker replaces once the graph arrives. The worker
answered and the reply was dropped, so the save promise never settled.

Listen for archive results with addEventListener so the population
client can own onmessage.

* test(core): drive the session worker open directly in the archive save test

IS_BROWSER is read once at import and Bun shares the module cache, so when another session test loads the reader first, parseFigFile took the main-thread path and the test passed without the fix. Export the worker open from read.ts and call it directly, release the worker afterwards, and drop the global window patch and the uncleared race timer.

fix(core): draw gradient and image strokes as the paint they are (#868)
* fix(core): draw gradient and image strokes as the paint they are

A stroke carried the paint vocabulary already, but nothing read it: the
.fig reader sent every stroke paint through resolvedPaintColor, which
returns black for a gradient or image, the renderer set a flat color on
strokePaint, and the writer emitted a SOLID paint.

Strokes now go through the same conversion fills do in both directions,
and applyGradientFill and applyImageFill take the target Paint so a
stroke reuses the fill shader path instead of growing a second one.
forVisibleStrokes is the single place every stroke draw passes through,
so the shader is set and cleared there rather than threaded through each
draw helper.

Closes #797 for rendering and .fig; authoring a gradient stroke from the
stroke panel is still to come.

* feat(app): author gradient and image strokes from the stroke panel

StrokeSection opened a solid-only colour picker and synthesised a fake
fill for the swatch, so a stroke could never be anything but one flat
colour. It now opens FillPicker like the fill panel does, and
applyStrokePaint keeps the stroke's weight, align, cap, join and dashes
across a paint change.

Completes #797.

* fix(core): let a gradient stroke reach vector outlines and arrowheads

A vector stroke draws its outline as a filled shape with fillPaint, a
dashed one strokes the path, and arrowheads are filled shapes of their
own; each cleared the shader first, so a gradient or image stroke on a
vector drew black. The stroke pass now configures both paints and owns
clearing them, and those helpers keep what it set.

Resolve each gradient stop against the stroke's own colour binding
rather than the stop's position, which looked up another stroke's.

Reported in review of #868.

* fix(core): release the shaders a paint no longer owns

Every gradient and image shader was handed to a paint and then leaked:
the paint takes its own reference, so the caller's handle has to go or
WASM memory grows with each redraw. Only the diamond branch did this.

A gradient stroke now configures two paints, which doubled the leak.

Reported in review of #868.

* test(render): model a shader handle the caller deletes

The pattern shader double returned a plain string, so deleting the
handle the paint no longer owns threw instead of passing.

fix(core): fill open subpaths of filled SVG paths (#876)
* fix(core): keep SVG icon stroke caps and joins after saving

Icons inserted from Iconify and vectors from import_svg set stroke-linecap
and stroke-linejoin only on the Stroke paint. .fig stores cap and join on
the node, and the reader rebuilds the paint's cap and join from it, so a
saved and reopened Lucide icon came back with NONE caps and MITER joins
and showed gaps where its strokes meet. Set strokeCap and strokeJoin on
the node as well.

* fix(core): fill open subpaths of filled SVG paths

SVG fills every subpath as if it were closed, but parseSVGPath put only
closed subpaths in the fill region. The renderer filled the open ones as
a separate path, so a hole formed by an open subpath and a closed one
under the path's fill rule was filled in, as in some Font Awesome icons.

Add an includeOpenRegions option to parseSVGPath, off by default, and set
it for filled paths without a stroke from Iconify icons and import_svg,
and for SVG clip paths. Stroked paths keep open subpaths out of the
region so their closing edges are not stroked. A filled polyline now
flattens with adjacent filled shapes like a polygon does.

* docs(changelog): state where open SVG subpaths are now filled

The app has no icon picker. The fix reaches Design JSX <Icon> and
inline <svg> through scalePathInfos, dropped and pasted SVG files and
clip paths through svgToVectorPaths, and makes filled polylines render
filled. Name the unstroked-path limit instead of an unqualified claim.

* test(core): import SceneGraph from its owning package

Scene Graph owns the graph type; the Core barrel only re-exports it for
compatibility. importVectors also returns the graph, matching the same
helper in #832 so the shared test files reconcile cleanly.

* docs(changelog): name every path that keeps SVG stroke caps

The app has no icon picker; the fix reaches Design JSX <Icon> and
inline <svg> through createIconFromPaths, and dropped or pasted SVG
files through the same vector placement as import_svg.

* test(core): import SceneGraph from its owning package

Scene Graph owns the graph type; the Core barrel only re-exports it
for compatibility.

* refactor(core): read the first SVG path stroke with at(0)

Array destructuring types the first stroke as always present, so the
type-aware no-unnecessary-condition lint rejected the guard that skips
vectors without strokes and failed bun run check.

test(fig): cover reopened instance overrides through component sync (#879)
* test(fig): cover reopened instance overrides through component sync

Instance overrides read from a saved .fig must survive the live editor's
main-component sync, a second save and reopen, and lazy population of a
later page through the session worker. Regression coverage for #750, which
the occurrence-scoped reader (#646) fixes.

* test(core): move reopened override coverage to its Core home

check:test-homes rejects new tests under tests/engine; the test drives createEditor and Core fig internals, so it belongs beside component-sync.test.ts. The second-save case passed on v0.15.1 and now runs as the tail of the first case.

fix(desktop): allow reading recent .fig files for thumbnails (#872)
* fix(desktop): allow reading recent .fig files for thumbnails

The recent-files thumbnail loader stats a .fig file, opens it, and seeks
and reads its thumbnail entry, but the desktop capability granted none of
those fs commands, so the WebView rejected the first call ("fs.stat not
allowed") and no thumbnail ever loaded. Grant stat and open with the same
path scope as read-file, plus the handle commands they lead to.

A native spec runs the loader's command sequence on a real .fig file.

* test(desktop): check the bytes the recent-file thumbnail read returns

The native spec discarded the read result, so a read returning nothing would pass. Assert the zip signature and the byte count the fs plugin appends, through a bytes variant of the native invoke helper.
